Image Upscaler
Image Upscaler enlarges a photo or graphic by 2×, 3× or 4× using stepped, high-quality resampling for a smoother result than a single big jump. It's handy when you need a bigger version of an image for print or display. Everything runs in your browser — nothing is uploaded, and there's no watermark. Note that resampling enlarges and smooths; it doesn't reconstruct detail that isn't there.

To upscale an image, choose a file and a scale (2×, 3× or 4×); the tool enlarges it in steps with high-quality smoothing and gives you a larger PNG. It runs in your browser — the image is never uploaded. It smooths as it enlarges but doesn't invent new detail the way AI super-resolution does.

Preguntas frecuentes
Is this AI super-resolution?
No. It uses high-quality browser resampling, which enlarges and smooths the image. It won't hallucinate fine detail like AI models, but it's instant, private and needs no huge model download.
Why is there a size limit?
Very large canvases can exhaust browser memory, so output is capped at 8000px per side. Choose a smaller scale for big source images.
Is my image uploaded?
No — upscaling happens entirely in your browser.
